4 barrel LA Intake

So, you've taken off the fuel management system, the TBI and replacing it with a carburetor to get better gas mileage? Tell me exactly how that is done and believe me I do understand what life is like, yet I would change out the granny 4 speed for a 5 spd NV3500 and before anyone says it's not strong enough, remember he's not gonna race and it came with many trucks like that..
